A good friend of mine recently stayed at our house with their kids. During the stay their partner smacked their 6 year old son on the back of the legs lightly for not doing as he was told.
I don't believe in smacking as punishment but I'm also not extremely judgemental on other parents deciding to do this. Context being the kids are great, their eldest is a sweetheart most of the time, they have always seemed great parents and I've never witnessed something like this before from them.
But my 4 year old witnessed the snack and instantly told the parent it wasn't kind, we shouldn't hit etc. It all kind of got swept away by changing the subject.
My OH now feels uneasy spending time with our friends now as we tell our son it's not acceptable to hit but he may witness it again.
So how would you handle it? I want to be respectful it's their decision how they parent but also it flys in the face of what we tell our son.
